- WINDING-MACHINE.

State of Rhode Island, have invented certain new and useful Improvements In-Winding- Machines, of which the following is a specification.

My invention relates to winding machines and consists particularly of improvements in the traverse-mechanism therefor.

' The object ofmy improvement is to provide means for, gradually shortening the traverse of the thread-guide from start to finish ofthe winding to cause the cop or quill to be wound with tapered or conical ends.

' A further ob] ect of my invention is to provide a traverse-shortening devicewhich can be applied to standard types of machines now generally known and used, without requiring any material change in the main -'parts of the mechanism thereof.

The invention is fully described in'the following specification, illustrated by the accompanying drawings, in which like letters of'reference designate like parts.

In the drawings :-Figure 1 is a front elevation of a usual type of winding machine 'o showing my'new traversecontrolling mechanism'applied thereto; Fig. 2 is an enlarged view of the essential parts of the new de-' vice; Fig. 3 is an end elevation of the same; Fig. .4 is a part sectional View, taken on the g line-XX of. Fig. 1, looking in the direc- (Lion-indicated by the arrow 00; Fig. 5 illustrates the style of cop or quill wound on machines fitted with my-improved device.

. Referring to Fig. 1, the machine in general; 40 as here shown, isof a wellknown type sub: stant'ially like that described and illustrated in United States Patent No. 589,587 granted to S. ,VV. lVardwell Sept. 7, 1897 and widely used for winding shuttle cops or quills by i the Universal or V-wind system. It consists essentially of-a rectangular frame A having parallel'uprights a, a formed with bearings for the horizontal winding-spindle B andcamrshaft C. The spindle B is driven through the medium of a driving-pulley 5 adapted to be rotated by a suitable belt, not here shown, which is shifted onto the loose pulley b. when it is desired to stop the machine.- The spindle B also carries a pulley Specification of Letters Patent.

hand-nut 6 b which is connected by abelt to a pulley on a shaft D. I The shaft D is mounted to rotate in hearings on a'frame cl which is pivoted at d',,d on the cam-shaft C. At one end the shaft D carriesa pinion (Z which meshes with a gear c on the cam-shaft C. The pulley b is preferably of the expansible type commonly used on winding machines of this style and can'be adjusted to vary the diameter of its rim by simply turning the Through this adjustment the ratio between the speed of the spindle B and that of the cam-shaft C can be varied to regulate the laying oftheyarn or thread by the reciprocating thread-guide in a manner well known to those versed in the art.

The cam C is mounted fast on the shaft 0 and is driven thereby, through the connections .-above described, to impart reciprocation to a horizontal traverse-bar E. The bar E is arranged parallel with the windingspindle B and is mounted to slide longitudinally in the bearings a, a of the frame A.

The bar E is preferably arranged to project from both sides of the frame A to adapt it to carry two thread-guides G so that the machine can be arranged to wind two quills at a time, one being supported at each end of the winding-spindle B. As both ends of the machine are similar, however, I have preferred to here illustrate the traverse- Patented May 23, 1916. Application filed July 21, 1913. Serial No. 780,275.

mechanism for one quill only, it being understood that this mechanism is duplicated on the opposite side of the frame A. 1

Arranged in'the rear of the traverse-bar E and supported fixedly in bearings a of the frame A, see Fig. 3,is a horizontal rod F extending parallel with the rod E. On the outer end of the rod F is supported a bracket H which carries anend-bearing h for the cop-tube a, see Fig. 2. The endbearing 71. preferably takes the form of a live spindle rotatable in a bushing 71. and projecting therefrom to enter the bore of the tube 2. The opposite end of the tube a is supported on the reduced end I) of the winding-spindle B and is preferably formed with a slot 2' which is engaged by a key or spline a as usually provided for in machines of this class.

The thread-guide G is mounted on the traverse-barfE Ithroughthe means of an armor holder G arranged to oscillate about the axis of the bar to allow the guide E is reciprocated from. the'cam-C through the engagement. of the groove in the lat- 'ter with a roll jcarried by a cross-head J attached to the'bar. One end of the-crosshead J surrounds the bar E and is'clamped thereon by means of the binder-screw 9'. At its opposite end the cross-head J is fitted to the under sidesof the rod F and a spring- Asusually provided in machines ojf this I I r p I l 'In my present improvement I maintain the reciprocation of the -traverse-bar uniform,

but provide for shifting the thread-guide longitudinally of the bar during the move- I ment of the latter so as to effect the gradual shortening of the traverse of the guide; from start to finish of thewinding'. To adapt the guide G forthisshifting movement in relation to the bar E itis mounted on a sleeve I g wh ch slides on the bar.

The guideholder G" is formed as a bifurcated arm.

A stud j isriveted in a hub 7" contact with the rear face of the guideat the center of the cross-head J and'serves holder G to limit the movement of the as a bearing for the roll j-which engages guide G toward the axis of the quill; while with the cam-groove c' j the other prongi g is'engaged by a flat The above described parts are.s11bstan-' spring g i'secured to theguide-holderGf at tially' the same in structure and arrangeits upper end by the screw 9''. The'end of ment as those employed generally in ma the spring g rides on the cam-face g of the chines of this type and mynew devices are prong g and tends to force; the guide G we applied thereto in the manner and for the toward the axis of the cop-tube, and-as the I 'pur ose as now described. 4 yarn is built up: thereon the movement of eretofore it has beenthecommon practhe guide away from the quill is resisted by ties to, reciprocate the thread-guide with a the action of the spring, so as to maintain constant traverse throughout the winding the guide alwaysbearingfirinly against'the of the cop or quill. This naturally results surface of thewinding. Attached to the in building up the ends of the quill' with a upper end of the guide 'holder G .is a guidflat formation; that is to say, the; ends will ing-eye 9 through which the yarn-or thread be square with the .axis of the quill. In leads from above, and thence it passes winding some varieties of thread, such as through a notch 9 in the gulde G,'see also hard, glossy silk and other like materials, it Fig. 2, and onto the cop-tube 2. The sleeve has been found very diflicult to build the g on which-the guide-holderGis mounted quills with perfect ends whileemploying is formedyvith a head '9 at one end, to this tyle f winding, Owing t th li .which is attached the end of a connecting-- pery quality of the thread the coilsof windrod or link K.

Mounted to turn12o im rovement will be next described. in bear1ng-1ugs-Z',-'l on sald bracket '18 a t will be observed from the foregoing rock-shaft having 1ts outerjend bent at" explanation that the traverse-bar E is given right-angles to form the crank-arm nag S e-l4 a' uniform reciprocation from the cam C- cured to'theend of the crank-arm m by a throughout the operation of the machine. screw m" is a hnk m formed with 1ts,lower type the thread-guide is fixedly attached to the traverse-bar, so that thegguide also has a constant extent-of traverse in-relation to idle B to adapt it to be secured to a swinging-f frame N. Referring particularly to Figs. 2 and 3, the. frame .Nis of fork-like .the cop-tube on which the quill is wound; construction having. a, hub -h pivoted on'th 13o rod F and two upwardly ciirvedi arms n, n.

The upper ends of the arms n, n are provided with slots WP, 14, adapted to receive the ends of a rod Or pin 0 which serves as an axial bearing for a pressure-roll O. The

roll 0 is preferably constructed of wood or other similar materialandhas a smooth, pe-

ripheral surface adapted to contact w1th the yarn or'thread as the latter is woundon the tube 2. The roll 0 is maintained in contact with the surface of the winding by means of weights ;0 suspended at the end of a rod P which extends rearwardlv from the frame N. Preferably the rod F is driven into an arm n projecting from the hub n of the frame N and the weights 1) are hung on a rod 39. suspended from a spring 1)? hooked into a hole p in the rod P. The spring 72 serves totake the shock of any sudden movement of the frame \N' and prevents the weights pfrom jumping up and down on a the rod 2. In this way the effects of momentu'm and inertia on the roll 0 are par-- tially compensated for. Thelink' m is secured to the inner arm n of the frame N by-any suitable means, such as the screw m and as the roll 0 .is forced downward by the increase in diameter or growth of the quill thecrank-arm m and rock-shaft M are havin turned in the direction indicated by the arrow 2, Fig. 3. Secured to the rock-shaft M between the bearing-lugs Z, Z is an arm R- its hub 1' clamped to the shaft by the binder-screw 1". The arm R extends -laterally from the shaft M'in the opposite direction from that of the crank-arm m and its outer end is reduced at 1' to adapt it to engage a hole 8 in a'vcrtical-slide S. 'As shown in Figs. 2 and 3, the slide S is relatively narrow portion s fitted to slide in a slot or guidewa-y 1* formed in the downpreferably formed of, sheet-metal with a wardly-extending member 71 of the bracket u L. The guideway Z might be constructed with dovetail edges fitted to the slide S to retain the latter'in place, but as here shown I preferto employ a cover or plate: 1 fastened to the bracket L by the screws Z Z. to

hold the slide in the guideway. At its upper .end the slide S is bent f orward in the rightangled arm 8 which is then bent downwardly again at. s and terminates in the relatively-long, guiding-member or track's formed with the horizontal slot-s It will be observed that the'rocking of the shaft.

through the slot 8 in the track 8 and is screwed into the, end of the arm t of the member T. The stud t is adapted to slide I in the slot 8 as the thread-guide G and its I connecting rod or link K reciprocatewith the traverse-bar E.

Referring to Figs. 2 and 4, U designates a rockable arm or lever formed at its upper .end with a longitudinal slot u.

F astened to the-frontof the bracket is a vertically-adjustable plate L-" which is held in position by the screws Z; Z extend .ing through the slotsV, Z TheplateL' bears against tworaised ledges or-end abutments i Z on the front of-the bracket L so that an open space is left between 'the rear face ofthe plate and the front face of the 'bracket throughout the greater portion of.

the length of the plate. In this Way the lever .U is adapted to be held in place againstthe front face of the bracket L and is arranged to pivoton a stud or pin'l pr0-. jecting rear-wardly from theplate L. The stud l engages theaslot u in'the lever U. to

allow the latter to slide up and down-during its sw'ingingmotion as it oscillates about the axis of the stud. By looseningthe screws'r I Z, Z the plate L can-be adjusted up ,and down on the bracket L to vary the position of its pivot stud Z" and in thisway the range of movement of the lever U can be.

altered as more particularly described hereinafter. The lever Uis givena reciprocatory-ro'cklng movement, somewhat like the link-motion of a steam-engine, through its connection with the reciprocating crosshead J. v

= Referring particularly tovFig. 4, which shows the slide S removed from in front of the lever U, a stud or pin u is riveted through'the lever U near its lower end and projects rearwardly therefrom to adapt it to engage a hole 1' in a lug j on the crosshea-d J. Secured against the front face of the lever U is abridge-member U formed with the inajor portion of its length oflset from the lever, so as to leave a space between the two.. The bridge-member U"is' fastened to thelever U by means of a screw u and stud andis formed with a longitudinal' slot u" extending throughout apart. I

Referring to Figs. 2, 3 and 4, theend ofthe link K oppositeto that connected with .the thread-guide G projects between'ithe.

outer, face of the lever'U and the inner face of the bridge-member U and carries alstud the studs u and M are' scored with pe- 18 of the winding, as illustrated in'Figs. '1 and ripheral grooves 11. and to, respectively, and

a coiled spring V is stretched between the studs with its ends hooked around said grooves. The tendency ofthe spring V is to draw the stud downwardly in theslot w.

The methodv of .operation of my com* plete device is as follows: The cop-tube z is placed in position by seating one of its ends on the end of the winding-spindle B and the other on the spindle-bearing it, and the yarn or thread y is led from .its source of supply throughthe guiding-eye g and notch g 'of'the thread-guide G and thensecured to the tube 2, Through the efl ect of the weights 1) Ion theframe P the pressure-roll.,O will be held. against the surface of\the tubes at thebeginning' 3. "When the machine, isstartedbyfshifting, the driving-belt on to the pulley b the spindle B: will rotate the tube a and, through its connections with the cam-shaft. W111. turn the 0am(]' to reciprocate the traversebar-E. Asthe yarn builds up on the tube a wardly, thereby swinging the frame N outhe "pressureroll 0 will be forced downthe rod F and causing the-linkm touturn the crank-arm m in the direction indicated w 4 shortened as the cop increases in diameter.

The result of this restriction orv shortening,

of the traverse .of the guide is to build the vquill with'thelayers of winding of gradually diminishing lengths so that the .ends of .thequill-take on atapered or conical formaby the arrow 2', Fig. .3. The movement of 'the crank-arm mturns the rock-shaft M-to ua-lly moved upwardly in its guideway Z9. on the bracket L.

- 'During the reciprocation of the crosshead J and traverse-bar E; the lever U,'

; whichfis connected with .the former b the pin to. is caused to oscillate backand forth 5 between the positions 'shownby =-fu11 lines and" dot-and-dash lines in Fig. 2, its upper end sliding on the p'vot-stud l". the

ding the link K is' held in the positionillustrated in Fig. 1 with the .stud n in the same horizontal plane with the screw 'gFat itsopposite end. .With the parts in this position :the link- K. will have a right-line, movement with respect to aliwe' described"the elb'ow member T and.

the cam ()"exactly equal to the reciproca tory. movement of the. traversear E, and

therefore the threadguide G lbe rm ers edwith the full extent of throw. of the bar.

As the; lever ,U- oscillates in the manner link K; which. are connected. thereto, movein synchronytherewith and the stud t? on th'earm' t"-$lides in'thev slot 8 of the guiding-tra ckus". Now, as the slide .S' and its track 8 are'raised. through the movement of. the roll O,-under the influence of the.

growth in diameterpf 'the. winding. the

stud u?- at the end -ofthe link K'will be moved gradually upward in the slot'u of the bridge-member U.

memberU' forms apart of the lever U the end of the K is therefore caused to to win Since the bridgegradually approach the a-iris of oscillation full lines in Fig. 2, the lever U will actto draw the link K inwardly so that the sleeve 4 g is. shifted on the; traverse-bar to hold the thread-guide from traversing through the I full extent of .throw of the bar. In'the same -way, when the traverse-bar E] is 'carried to' theoppos1te extreme of its throw the lever U will have been rocked to the position the link ill be moved in the other direction, "or outwardly-withrespect to thetravshown by'dot-and-dash linesin F ig..2, and 11 erse'bar, so that thethread-guidewill 1 be prevented from continuing the full extent of traverse inwardly with the bar, In this, -way the movement of the thread-guide G is restricted or retarded at the end of each a stroke of the traverse-barand thereby the extent of'traverse .ofthe' guide is gradually tionas illustrated by the outline Y in Fig.

in-Fig. 5. I v I By adjusting the plate L'- up and down 2,'and,by the more complete representation 0n the bracket the. pivot Z for the lever -U can beraised or lowered to alter the range ,of action of the lever U. --Thro.ugh' this means the angularity ofjthe lever U with i I respect to the traverse-bar E at the'extremes of its oscillation can be increased or dimin- 'ish'edasrequired to effect a greater or less limitation or shorteningof-the'traverse of the thread-guide. I .In this way the degree of taper at; the ends of the quill can 'flbevaried as desired or ;in accordance ith dif jferent'conditionsgin the winding or of. the materials being wound. When it is re- 'quired to wind quills of difl'erent .length' a. cam of different throw is' substituted for the cam G andstheconnection of the .link I K to the guide G is adjusted through the means of the holes 7:; as previously described.

I am. aware that it is notvnew in the art and I am familiar with several and various devices for accomplrShmg this purpose. Heretofore; however so far as 'I am aware cops or quills with conical ends no mechanism for this purpose has been de-.

vised which is capable of I beinglattziched' to 'standard types of winding-machines, already in-use,- without affecting the general ating parts thereof. Furthermore, it is my belief that the present inventionis the first wherein the traverse-bar on which 1 the thread-guide is mounted is given a constant i extent of reciprocation While the guide itself is shifted thereon through automaticallyoperated means toicausea shortening of its traverse as the cop increases in diameter.

Various modifications might be made in the form and structure of the parts of my device without departing from the spirit or scope ofthe invention; therefore,
